What to Look for While Buying a Smart Thermostat
When you’re in the market for a new smart thermostat, there are a few features you’ll want to keep an eye out for:Ease of use
A good smart thermostat should be easy to set up and use — you shouldn’t need an engineering degree to figure out how to program it.Compatibility
Make sure that the smart thermostat you’re considering is compatible with your home’s heating and cooling system, or else it won’t do you much good.Energy savings
One of the main reasons to buy a smart thermostat is to save money on your energy bills. Look for a device that offers energy-saving features such as scheduling and auto-adjustment.HVAC system
When shopping for a smart thermostat, you must consider your home’s heating and cooling system. If you have a central air conditioner, you’ll want a line-voltage model to handle the high voltage required by this type of AC unit. If you have a low-voltage system, such as a heat pump, you can choose either a line-voltage or low-voltage smart thermostat.Wiring
Once you’ve determined which type of smart thermostat is compatible with your HVAC system, look at your existing thermostat’s wiring. If there are only two wires (one red and one white), you have a low-voltage system and can choose a line-voltage or low-voltage thermostat. If there are more than two wires, you have a line-voltage system and will need to buy a line-voltage smart thermostat.Smart Thermostat Features
Some common features of smart thermostats include:Auto changeover switch
This feature automatically switches your smart thermostat between heating and cooling modes depending on the temperature inside your home. This feature is handy in places where days are hotter than nights.Remote access
You can remotely adjust the temperature in your home using your smartphone or other mobile devices. This is especially handy if you forget to set your smart thermostat’s temperature before leaving for work or going to bed.Energy usage reporting
Smart thermostats keep track of your energy usage and provide detailed reports, which can help you save money by changing your daily routine to use less energy.Smart controls
Some smart thermostats can be controlled using an app on your smartphone or tablet, while others can be controlled using voice commands. This hands-free control is convenient and can help you save time and your own energy, not to mention heating and cooling energy.Geofencing
Geofencing is a smart thermostat feature that uses GPS to automatically adjust the temperature of your home when you’re away. This helps make sure that your home is always comfortable, even when you’re not there.Benefits of Using Smart Thermostats
There are many benefits of using smart thermostats, including saving money on your energy bills, being able to control your home’s temperature from anywhere, and the peace of mind that comes with knowing your home is always comfortable.Energy savings
One of the most significant benefits is the energy that you can save. Smart thermostats are designed to be more efficient than traditional thermostats and can help you save energy more effectively. They also have features like scheduling and energy-usage tracking to make it easier for you to conserve energy.Cost savings
Another way smart thermostats can help you save money is by reducing the cost of your energy bill. These thermostats are more efficient than traditional thermostats because they use less energy to heat and cool your home — according to Energy Star, you can save up to $180 per year on your energy bill by switching to a smart thermostat.
